Description

Technical Field

[0001] The utility model belongs to the technical field of water outlet pools, and specifically relates to an adjustable stop log for a water outlet pool. Background Technique

[0002] During the construction of siphon water supply, the outflow effect at the water outlet of the water outlet pool is greatly affected by the downstream water level. When the downstream river water level is low, the water outlet pool can meet the requirements of siphon submerged outflow, and the outflow is normal; when the downstream river water level is high, due to the outflow being blocked by the baffle on the downstream side of the water outlet pool, the water level in the water outlet pool rises significantly, 30 - 50 cm higher than the normal water level, reducing the water level difference between upstream and downstream. Since the siphon pipeline water supply mainly relies on the pressure formed by the water level difference between upstream and downstream to provide power for siphon water supply, the traditional water outlet pool structure has limited adjustment ability in dealing with water level and water volume changes, easily causing uneven water flow or water level rise, affecting the overall water supply effect.

[0003] Therefore, how to effectively solve the problem that the water outlet pool structure has limited adjustment ability in dealing with water level and water volume changes, and is prone to cause uneven water flow or water level rise is a technical problem to be solved urgently. Content of the Utility Model

[0004] In view of the deficiencies in the above background technique, the present utility model proposes an adjustable stop log for a water outlet pool, which solves the problems that the water outlet pool structure has limited adjustment ability in dealing with water level and water volume changes, and is prone to cause uneven water flow or water level rise.

[0005] The technical solution of this application is as follows:

[0006] An adjustable stop log for a water outlet pool, including a water outlet pool, a drain pipe is connected to the upstream of the water outlet pool, and a height-adjustable stop log unit is arranged downstream. A first sealing structure is arranged between the stop log unit and the water outlet pool. The stop log unit includes a horizontal blocking member detachably connected to the water outlet pool. The height of the stop log unit can be adjusted in a timely manner according to the outflow situation, thereby adjusting the water level and flow rate of the water outlet pool, being able to flexibly adapt to different flow rate requirements, effectively controlling the water level and flow rate of the downstream water outlet pool, ensuring the efficient operation, energy conservation and environmental protection of the water supply system, and achieving more accurate flow rate control; it can effectively control the water flow, reduce water resource waste, reduce the maintenance cost, the annual water saving rate can reach 10% - 15%, improving the utilization efficiency of water resources; using local materials, being convenient for installation and disassembly, simple and effective in production, and saving costs.

[0007] Furthermore, a plurality of the horizontal blocking members are arranged, and a second sealing structure is arranged between adjacent horizontal blocking members. When more horizontal blocking members are stacked, the height of the water outlet of the water outlet pool is higher. The height of the stop log unit is adjusted in a timely manner according to the outflow situation, thereby adjusting the water level and flow rate of the water outlet pool.

[0008] Further, a chute is provided on the inner wall of the water outlet tank, and a first sealing structure is arranged in the chute. The horizontal stop member includes a first stop rod, and convex blocks are arranged at both ends of the first stop rod. The convex blocks are slidably matched with the chute.

[0009] Further, the first sealing structure includes an airbag provided with an air inlet hole and an air outlet hole. When the first stop rod is in place, the airbag is pressed between the convex block and the chute. The airbag not only limits the horizontal stop member, preventing displacement under the impact of water flow, but also effectively fills the gap between the chute of the water outlet tank and the horizontal stop member, preventing water leakage.

[0010] Further, the airbag is arranged along the length direction of the chute, and the airbag is in a bag shape.

[0011] Further, the second sealing structure includes sealing strips arranged on the top surface and the bottom surface of the first stop rod.

[0012] Further, the horizontal stop member includes an upper stop rod and a lower stop rod which are in plug-in fit. Convex blocks are arranged at both ends of the upper stop rod and the lower stop rod and are slidably matched with the chute. The second sealing structure further includes a first baffle arranged at the downstream end of the upper stop rod and a second baffle arranged at the upstream end of the lower stop rod.

[0013] Further, the inner surface of the first baffle is attached to the outer surface of the lower stop rod, and the inner surface of the second baffle is attached to the outer surface of the upper stop rod.

[0014] Further, the top and bottom of the first baffle are flush with the midpoints of the adjacent second baffles. After the upper stop rod and the lower stop rod are stacked together, the second baffle and the first baffle can block the gap between the upper stop rod and the lower stop rod, further effectively preventing water leakage.

[0015] Further, a cross beam is arranged at the top of the water outlet tank to prevent the water outlet tank from deforming.

[0016] The specific beneficial effects of the present utility model include:

[0017] 1. The present utility model can adjust the height of the laminated beam unit in a timely manner according to the outflow situation, thereby adjusting the water level and flow rate of the water outlet tank, being able to flexibly adapt to different flow rate requirements, effectively controlling the water level and flow rate of the downstream water outlet tank, ensuring the efficient operation, energy conservation and environmental protection of the water supply system, and achieving more accurate flow rate control;

[0018] 2. Through the airbag in the first sealing structure, it not only limits the horizontal stop member, preventing displacement under the impact of water flow, but also effectively fills the gap between the chute of the water outlet tank and the horizontal stop member, preventing water leakage;

[0019] 3. The utility model is simple to manufacture, convenient to install and disassemble, and cost-saving. Brief Description of the Drawings
